Springs
Warning
Use caution when tensioning the springs as they
are under heavy load.
The counterbalance springs help balance the cutting units to
allow equal amounts of weight (down pressure) to be
distributed to each end of the cutting unit. The springs also
transfer weight from the cutting units to the traction unit
therefore, increasing traction.
The following are recommended settings for the
counterbalance springs. Minor changes may be required to
achieve optimum performance for your turf conditions. The
weight, at each end of the cutting unit, can be checked
easily with a spring scale.
• Increasing the spring tension reduces the weight on
inboard end of the cutting unit and increases theweight on the outboard end.
• Decreasing the spring tension increases the weight on
the inboard end of the cutting unit and reduces the
weight on outboard end.
Reelmaster 2300
1. Hook the spring into the third hole from the top on the
inboard side of both front cutting unit lift tabs and on

Important Due to the nature of biodegradable fluids, it
is critical that the fluid be changed at the recommended
intervals or severe hydraulic component damage may
occur.
Note: The fluid in this group is not compatible with the
fluids in group 1.
Important These hydraulic fluids are specified to allow
optimal operation of the machine in a wide range of
temperatures encountered. The group 1 fluids are a
multi-viscosity hydraulic fluids which allows operation at
lower temperatures without the increased viscosity, which
is associated with straight viscosity fluids.
Note: When changing from one type of hydraulic fluid to
the other, be certain to remove all the old fluid from the
system, because some brands of one type are not
completely compatible with some brands of the other type
of hydraulic fluid.
Important Use only types of hydraulic fluids specified.
Other fluids could cause system damage.

1. Hydraulic reservoir cap2. Sight gauge
Important To prevent system contamination, clean the
top of the hydraulic fluid containers before puncturing.
Ensure that the pour spout and funnel are clean.
4. Install the reservoir cap. Wipe up any fluid that may
have spilled.
Inspecting the Fuel Filter
Inspect the fuel filter bowl daily for water or other
contaminants. If water or other contaminants are present,
they must be removed before commencing operation.
1. Close the fuel shut-off above the filter (Fig. 26).
2. Unscrew the nut securing the bowl to the filter head.
Remove water or other contaminants from the bowl.
Note: A red dye additive for the hydraulic system fluid is
available in 2/3 oz bottles. One bottle is sufficient for 4–6
gal. of hydraulic oil. Order Part No. 44-2500 from your
Authorized Toro Distributor.
1. Position the machine on a level surface.
2. Check the fluid level by viewing it in the sight gauge
(Fig. 25). If the fluid is cold, the level should be at the
bottom of the gauge. If the fluid is hot, the level should
be at the center of the gauge.
3. If the fluid level is not at least at the bottom of the
gauge when it is cold, remove the cap from the
hydraulic fluid reservoir (Fig. 25) and slowly fill the

Checking the Tire Pressure
The tires are over-inflated for shipping. Therefore, release
some of the air to reduce the pressure. The correct air
pressure in the tires is 16–20 psi (110–138 kPa).
Important Maintain the recommended pressure in all
tires to ensure a good quality-of-cut and proper machine
performance. Do not under-inflate.
Checking the Reel to Bedknife
Contact
Each day before operating, check the reel to bedknife
contact, regardless if the quality of cut had previously been
acceptable. There must be light contact across the full
length of the reel and bedknife; refer to Adjusting the Reel
to the Bedknife in the Cutting Unit Operator’s Manual.

4. With the operator on the seat, the engine running, and
the reel switch in the ON position, the dash indicator
light should be glowing and the reel motors turning
when the lift cylinder is fully retracted. As the lift
cylinder is extended, the light should go out and the reel
motors should stop turning. Correct the problem if it is
not operating properly.
5. With the operator on the seat, the engine must not start
with either the reel switch engaged or the traction
control engaged. Correct the problem if it is not
operating properly.

Checking the Operation of the
Interlock Switches
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
• Replace switches every two years regardless of
whether they are operating properly or not.
In case of an emergency, the machine can be towed for a
short distance. However, we do not recommend this as a
standard procedure.
Important Do not tow the machine faster than 2–3
MPH because the drive system may become damaged. If
the machine must be moved a considerable distance,
transport it on a truck or trailer.
1. Locate the bypass valve on the pump (Fig. 37) and
rotate it 90° (the bypass valve lever should be
horizontal when it is open).
1
Figure 37
1. Bypass valve
28
Page 29
2. Before starting the engine, close the bypass valve by
rotating it 90° (the bypass valve lever should be
vertical when closed). Do not start the engine when the
valve is open.
1. Verify the height-of-cut setting on the cutting units.
Using the column of the chart listing either 5 or 8 blade
reels, find the height of cut listing nearest the actual
height-of-cut setting. Look across the chart to find the
number corresponding to that height of cut.
Operating Characteristics
Caution
This machine produces sound levels in excess of
85dBA at the operators ear and can cause hearing
loss through extended periods of exposure.
Wear hearing protection when operating this
machine.
Practice operating the machine and become thoroughly
familiar with it. Because of its hydrostatic transmission and
choices or two or three wheel drive (model 03427 only), its
characteristics differ from many turf maintenance
machines. Points to consider when operating are the
traction drive, engine speed, and load on the cutting units.
Regulate the traction pedal to keep the engine RPM high
and somewhat constant while mowing to maintain adequate
power for the traction and cutting units. Adjust the speed
selector to maintain constant ground speed and quality of
cut. However, when on hilly terrain, do not use the speed
selector.
Follow the operating guidelines presented in this manual
and know how to operate the machine safely on all types of
terrain. Use the Slope Chart, page 9, to assist in
determining slope angles of questionable areas. Hills (or
slopes) over 15 degrees should be traversed or mowed up
and down, not side to side, and hills over 20 degrees should
generally be avoided unless special safeguards, skills, and
conditions exist. Always plan well ahead to avoid the need
for sudden stops, starts, or turns. To stop, use the reverse
pedal for braking. Before stopping the engine, disengage all
controls, move the throttle to the lDLE position, and set the
parking brake.
2. Turn the reel speed control knob (Fig. 38) to the number
setting determined in step 1.
1
Figure 38
1. Reel speed control
3. Operate the machine for several days, then examine the
cut to ensure satisfaction with the quality of cut. The
reel speed knob may be set one position on either side
of the position indicated on the chart to account for
differences in grass condition, grass length removed,
and personal preference of the superintendent.
Before mowing with the machine, we suggest that you find
a clear area and practice starting and stopping, raising and
lowering cutting units, turning, etc. This training period
will be beneficial to the operator in gaining confidence in
the performance of the machine.
Before Mowing
Inspect the area for debris and clear area if necessary.
Determine the best direction to mow on the previous
mowing direction. Always mow in an alternate pattern
from the previous mowing, so that the grass blades will be
less apt to lay down and therefore be difficult to gather
between the reel blades and bedknife.
Transport Operation
Be sure that the cutting units are in the fully up position,
move the traction pedal stop from under the pedal to allow
full traction pedal travel, and place the throttle control in
the FAST position. While operating on slopes and uneven
terrain, always reduce your speed and use extreme caution
before turning to reduce the risk of tipping or losing
control. Watch carefully for, and avoid, holes in the terrain,
sudden drop-offs, and other hidden hazards. To prevent
costly damage and down time, familiarize yourself with the
width of the machine. Do not attempt to pass between
immovable objects placed close together.
* This height-of-cut and/or mowing speed not recommended for
8 blade reels.
Inspection and Clean-Up After
Mowing
At the completion of the mowing operation, thoroughly
wash the machine with a garden hose—without a
nozzle—so that excessive water pressure will not cause
contamination and damage to the seals and bearings.
Make sure that the radiator screen, radiator, and oil cooler
are kept free of dirt or grass clippings. After cleaning, it is
recommended that the machine be inspected for possible
hydraulic fluid leaks, damage or wear to the hydraulic and
mechanical components, and the cutting units checked for
sharpness and proper reel to bedknife adjustment.

Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do any
maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
Greasing the Bearings and
Bushings
The traction unit has grease fittings that must be lubricated
regularly with No. 2 General Purpose Lithium Base Grease.
If the machine is operated under normal conditions,
lubricate bearings and bushings after every 50 hours of
operation. Bearings and bushings must be lubricated daily
when operating conditions are extremely dusty and dirty.
Dusty and dirty operating conditions could cause dirt to get
into the bearings and bushings, resulting in accelerated
wear.
The traction unit bearings and bushings that must be
lubricated are: steering column (Fig. 39), steering gears (2)
(under the skirt below the steering sector), steering shaft (2)
(Fig. 40), lift arms (3) (Fig. 41), pivot rods (3) (Fig. 42),
rear lift cylinder pivot (Fig. 43), traction pedal pivot
(Fig. 44) and rear wheel (2WD only) (Fig. 45)

soak the filter element about 15 minutes. Refer to
the directions on the filter cleaner carton for
complete information.
B. After soaking the filter for 15 minutes, rinse it with
clear water. Maximum water pressure must not
exceed 40 psi to prevent damage to the filter
element. Rinse the filter from the clean side to the
dirty side.
C. Dry the filter element using warm, flowing air
(160°F max.), or allow the element to air-dry. Do
not use a light bulb to dry the filter element because
damage could result.
5. Compressed Air Method
A. Blow the compressed air from the inside to the
outside of a dry filter element. Do not exceed
100 psi to prevent damage to the element.
B. Keep the air hose nozzle at least 2 in. (51 mm) from

pressure to the outer rim of the filter when installing.
Do not press on the flexible center of the filter.
8. Install the cover and secure the latches. Make sure that
the cover is positioned with the TOP side up.
Cleaning the Radiator and
Screen
To prevent the system from overheating, the radiator
screen, radiator, and oil cooler must be kept clean. Check
the screen, radiator, and oil cooler daily and, if necessary,
clean any debris off of these parts. Clean these components
more frequently in dusty dirty conditions.
1. Remove the radiator screen (Fig. 49).
2. Working from the fan side of the radiator, either spray
the radiator with a hose or blow it with compressed air.
Changing the Engine Oil and
Filter
Change the oil and filter initially after the first 20 hours of
operation. Thereafter, change the oil every 50 hours and the
filter every 100 hours.
1. Locate the engine oil drain plug on the bottom of the oil
pan. Remove the drain plug and let the oil flow into the
drain pan. When the oil stops, install the drain plug.
2. Locate the engine filter on the front of the engine.
Remove the oil filter. Apply a light coat of clean oil to
the new filter seal before screwing it on. Do not
over-tighten.
3. Add oil to the crankcase; refer to Checking the
Crankcase Oil, page 21.
Changing the Hydraulic
System Fluid and Filter
The hydraulic system filter must be changed initially, after
the first five hours of operation, and thereafter every 200
hours of operation or yearly, whichever comes first. Use a
genuine Toro oil filter for replacement. The hydraulic fluid
must be changed every 400 hours of operation or yearly,
whichever comes first.

3. Remove and inspect the fuel filter. Replace it if it is
dirty.
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
Adjusting the Transmission for
Neutral
If the machine “creeps” when the traction control pedal is
in the neutral position, the neutral return mechanism must
be adjusted.
1. Block up under the frame so one of the front wheels is
off of the floor. Place the selector control in the two
1
wheel drive position.
2. Start the engine, move the throttle to SLOW, and check
the front wheel that is off of shop floor; it must not be
rotating. Loosen the pump plate nuts and rotate pump
plate (Fig. 55) until creep does not occur in either
direction. When the wheel stops rotating, tighten the
nuts to lock the adjustment. Verify the adjustment with
the throttle in the SLOW and FAST position.

• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
4. Install the bowl to the filter head. Make sure that the
o-ring is positioned properly between the bowl
mounting nut and filter head.
5. Open the fuel shut-off above the filter (Fig. 54).

C. Tighten the locknut
Adjusting the Belts
Make sure the belts are properly tensioned to ensure proper
operation of the machine and prevent unnecessary wear. On
new belts, check the tension after 8 hours operation.
Hydraulic Pump Belt
A new hydraulic pump belt should be tensioned so that it
deflects 0.12 inch with a 15–17 pound load applied midway
in the span of the belt. A used belt should be tensioned so
that it deflects 0.12 inch with a 11–13 pound load applied
midway in the span of the belt.
Tighten the nut on the adjustment rod (Fig. 56) until the
desired belt tension is attained.
Note: Tighten the belt to eliminate slippage (squealing
under load) but do not overtighten.

2. Loosen the locknut securing the damper pivot to the
damper bracket (Fig. 58).
3. Depress the traction pedal fully forward.
4. Fully compress the damper and then release it, allowing
it to extend 0.08 in. Tighten the locknut securing the
adjustment.
5. When the traction pedal is fully depressed in the
rearward direction, the damper must contact the reverse
stop before extending the damper.
Adjusting the Hand Brake
1. Remove both front wheels.
2. Make sure that the brake is in the OFF position.
3. Loosen the jam nut on the clevis. Remove the cotter pin
securing the top of the clevis to the upper brake lever
(Fig. 59). Rotate the clevis, one turn at a time, to
decrease the distance between the levers.
The battery electrolyte level must be properly maintained
and the top of the battery kept clean. lf the machine is
stored in a location where temperatures are extremely high,
the battery will run down more rapidly than if the machine
is stored in a location where temperatures are cool.
Check the electrolyte level every 25 operating hours or, if
machine is in storage, every 30 days.
Maintain the cell level with distilled or demineralized
water. Do not fill the cells above the bottom of the split ring
inside each cell. Install the filler caps with the vents
pointing to the rear (toward the fuel tank).
Danger
Battery electrolyte contains sulfuric acid which is a
deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact with
skin, eyes or clothing. Wear safety glasses to
shield your eyes and rubber gloves to protect
your hands.
• Fill the battery where clean water is always
available for flushing the skin.

jam nut. Repeat the procedure on the opposite side of
the machine.
5. After any brake adjustment, operate the vehicle at a low
speed (one MPH or less) and check that the brakes
engage equally on both wheels. Readjust as necessary.
3. Clevis
Keep the top of the battery clean by washing it periodically
with a brush dipped in ammonia or bicarbonate of soda
solution. Flush the top surface with water after cleaning.
Do not remove the fill caps while cleaning.
Battery cables must be tight on the terminals to provide
good electrical contact.
Warning
Incorrect battery cable routing could damage the
machine and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
If corrosion occurs at the terminals, disconnect the cables,
negative (—) cable first, and scrape clamps and terminals
separately. Reconnect the cables, positive (+) cable first,
and coat the terminals with petroleum jelly.

Page 41
Storing the Battery
If the machine will be stored more than 30 days, remove
the battery and charge it fully. Either store it on the shelf or
on the machine. Leave the cables disconnected if it is stored
on the machine. Store the battery in a cool atmosphere to
avoid quick deterioration of the charge in the battery. To
prevent the battery from freezing, make sure it is fully
charged. The specific gravity of a fully charged battery is
1.265 – 1.299.
Fuses
The fuses in the electrical system are located on the back of
the instrument panel (Fig. 60).
Backlapping
Danger
While backlapping, the reels may stall and then
restart. Placing your hands or feet in the reel area
while backlapping will result in injury or death.
• Never place hands or feet in the reel area while
the engine is running.
• Do not attempt to restart the reels by hand or
foot.
• Do not adjust the reels while the engine is
running.
• If the reel stalls, stop the engine before
attempting to clear the reel.
